Safety signage and protective buoys are up, with the public being asked to “urgently avoid” the area.
The SHA is releasing a surplus of water, which will accelerate through the weekend leading to a total outflow of 900 cubic metres per second.
“The high water levels and spillway release often attract the attention of recreational boaters, but there is both a personal and operational safety risk that could occur if boaters ignore safety signage and pass the protective log boom into the inlet channel,” says the WSA.
“This could potentially trigger a situation a vessel could physically not escape the current and be drawn into the spillway structure.”
The public is also asked to remain on the roadway and to not approach the spillway by going down the embankment or standing along the wing walls.
All recreational boaters and visitors to the area are reminded to take a wide berth of the spillway, especially in the coming days.
